Backup Policy

MarkLogic Data Hub Service provides the following backup and retention policies:

Database Backup Policy

MarkLogic Data Hub Service performs two types of backups: full and incremental. These backups are performed by default on all services.

Full Backup backs up the following databases on a weekly basis: data-hub-JOBS (Saturday 5:20am UTC), data-hub-MODULES (Saturday 5:25am UTC), data-hub-FINAL (Saturday 5:30am UTC), and data-hub-STAGING (Saturday 1:30pm UTC).

Incremental Backup backs up the following databases on a daily basis: data-hub-JOBS (4:15am UTC), data-hub-MODULES (4:30am UTC), data-hub-FINAL (4:45am UTC), and data-hub-STAGING (5:00am UTC).

Note: Data Hub Service follows a unified UTC time instead of its local time zone. The backup start time is designed to avoid daylight saving time in all US time zones.

Both types of backup:

  • Back up Security, Schemas, and Triggers databases
  • Do not include replicas
  • Do not archive journals
